Market For 1959 To 1982 Circulated Pennies

They are coins (usually US cents) that have been rolled to an oval shape and stamped with a commemorative design. You'll find machines that press these coins in theme parks, zoos and other tourist attractions. Many people collect them. The more recent zinc cents aren't suitable for squashing as they turn out all streaky and grey, so most elongated collectors save pre-1982 copper cents to roll. I am sure some would be happy to pay for a quantity rather than have to sort through lots of rolls from the bank to pull out the pre-1982 ones.
There is a CCF thread on them here:
